AstralPool - Mechanical Seal Flange for Colusa Pump - 4405010793

AstralPool – Mechanical Seal Flange for Colusa Pump

This is the genuine AstralPool mechanical seal flange (position 17 in the official Fluidra exploded view) for the Colusa pool pump range. The flange locates and retains the mechanical seal between the motor shaft and the pump body, forming the critical barrier that prevents water from migrating along the shaft and into the motor. Replacing a worn or damaged flange promptly protects the motor and maintains leak-free pump operation.

Compatibilitate

This part is designed exclusively for the AstralPool Colusa pump (parent SKU 70579). The Colusa is a self-priming pool circulation pump available from 0.5 HP to 3 HP in single-phase and three-phase versions. Always cross-reference the exploded view diagram (position 17) or your pump’s documentation before ordering to confirm fitment for your specific Colusa variant.

De ce autenticitatea contează

As an official AstralPool OEM spare part, this flange is manufactured to the exact dimensional and material tolerances of the original component. Using a genuine part ensures correct seating of the mechanical seal, preserving the pump’s warranty and avoiding the premature failures that can result from ill-fitting aftermarket alternatives. The Colusa features a stainless steel motor shaft and sealed bearings, so maintaining the integrity of the mechanical seal assembly is essential to the pump’s longevity.

Instalare

Fitting this flange requires draining the pump, removing the motor, and disassembling the pump body to access the mechanical seal housing. The work involves close tolerances and familiarity with pump internals, so installation by a qualified pool technician or engineer is strongly recommended. Refer to the official Fluidra exploded view diagram (position 17) to ensure correct orientation and reassembly sequence.
